A freeze on the please wait screen has been a symptom of the "Expansion/Caching memory" ie.., the SD card, Msata, or EMMC for a long time.. A few early signs of it starting to read fail are, slow screen response, slow entrance into sim mode, long please waits, and long sharp logo waits. SD, and Msata can be cloned from a known good source, EMMC (which a 3050 has), will have to come from sharp for now. As of now I do not think a way of cloning them has been found out yet..
